Abstraction is the method of hiding the unwanted information. Whereas encapsulation is a method to hide the data in a single entity or unit along with a method to protect information from outside. We can implement abstraction using abstract class and interfaces.Encapsulation means hiding the internal details or mechanics of how an object does something. Abstraction is outer layout in terms of design. For Example: – Outer Look of a iPhone, like it has a display screen. Encapsulation is inner layout in terms of implementation.Abstraction is a feature of OOPs that hides the unnecessary detail but shows the essential information. Encapsulation is also a feature of OOPs. It hides the code and data into a single entity or unit so that the data can be protected from the outside world. It solves an issue at the design level.
